Pyrite Mineral | Uses and Properties - Geology.com

Pyrite is composed of iron and sulfur; however, the mineral does not serve as an important source of either of these elements. Iron is typically obtained from oxide ores such as hematite and magnetite. These ores occur in much larger accumulations, the iron is easier to extract and the metal is not contaminated with sulfur,...

University of Minnesota's Mineral Pages: Pyrite

Despite being a common, iron-rich mineral, pyrite is rarely mined for its own sake, and most of our iron is produced from magnetite and hematite deposits. Those iron oxide minerals occur in larger concentrations and volumes than pyrite, so they are a more economical iron source. Vein pyrite, however, may reveal the...

Pyrite - Wikipedia

The mineral pyrite, or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2 (iron(II) disulfide). Pyrite is considered the most common of the sulfide minerals. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's...
